OK, so I'm watching, today the wrasse is back to his perfect pristine self. Spot's spot is lessened, which seems to me to be bec. the scale is laying back down better. There was a bubble on his tail I thought was another spot but no, thank god. *^$#&*())!!!!!!!!!!!! MICROBUBBLES.
ANYway, no further spots, no one else has them. The observation continues with a 10g QT cycling in the kitchen JIC.
